Abstract

The invention is concerned with a method of adsorbing uniformly onto preformed high surface area crystalline alumina one or more catalytically active non-noble (doping) oxide(s) and preferably alumina-stabilizing non-noble doping oxide(s), both from substantially neutral aqueous colloidal solutions thereof, drying and calcining the doped alumina to form an improved washcoating composition for receiving additionally catalytic noble metal particles.
